It seems that the terms defined in this article are different from those used in other literature. Usually, left (right, respectively) annihilator is defined to be a left (right, respectively) ideal, not a right (left, respectively) ideal. (See, for example, /info/en/?search=Baer_ring) Any thoughts?

• It sounds like you are correct, and since it doesn't affect the definition, I think it should be changed. Minimalrho ( talk) 01:06, 12 January 2019 (UTC) reply
